About CFL Chemische Fabrik Lehrte
CFL Chemische Fabrik Lehrte has been producing high-purity inorganic salts since 1888 at its site in Lehrte near Hanover. The portfolio includes calcium chloride, magnesium chloride, magnesium sulfate, sodium sulfate, sodium chloride and potassium polysulfide as well as custom formulations, salt mixtures and salts with anti-caking additives. The value chain ranges from the production of solutions to crystallization, drying, mixing and milling through to packaging and repackaging according to customer requirements. Production, laboratory, warehouse and administration operate in accordance with GMP guidelines based on a QM system under DIN EN ISO 9001. The products meet the requirements of the pharmaceutical, food and cosmetics industries and are exported to over 45 countries. Since the acquisition by Sebastian Reichenbach and Daniel F. Schüssler in 2014, the entrepreneur-led company with more than 40 employees has been investing in process optimization, production, laboratory and logistics.
